You usually have to explictly opt-in to installing an Oracle JDK because... you know, they have a license agreement that you must agree to.

So there's no friction, everyone uses the OSS ones unless you have very specific needs.

Can you explain what the friction is ? If you download and install the ActiveState Python distribution in a commercial setting and accept the license agreement without reading and get sued legally at a later point, will you say Python has too much friction ?

Just go to https://openjdk.org/ and click "Download". Or say `brew install openjdk` (macOS) / `apt install openjdk` (linux).

ZERO friction.

There is no friction. Don't use commercial products if you don't want to pay for them. End of story.
